working with EXC_BAD_ACCESS scenarios When Using NSCache with Custom Objects in Objective-C
I'm migrating some code and I tried several approaches but none seem to work... I'm working with an `EXC_BAD_ACCESS` behavior when trying to use `NSCache` to store instances of a custom class in my Objective-C project. The class implements `NSCoding`, and I'm attempting to cache instances after fetching them from a remote API. The code looks like this: ```objective-c @interface MyCustomObject : NSObject <NSCoding> @property (nonatomic, strong) NSString *identifier; @property (nonatomic, strong) NSString *data; @end @implementation MyCustomObject - (void)encodeWithCoder:(NSCoder *)coder { [coder encodeObject:self.identifier forKey:@"identifier"]; [coder encodeObject:self.data forKey:@"data"]; } - (instancetype)initWithCoder:(NSCoder *)coder { if (self = [super init]) { _identifier = [coder decodeObjectForKey:@"identifier"]; _data = [coder decodeObjectForKey:@"data"]; } return self; } @end NSCache *myCache = [[NSCache alloc] init]; MyCustomObject *object = [[MyCustomObject alloc] init]; object.identifier = @"1"; object.data = @"Some data"; [myCache setObject:object forKey:object.identifier]; MyCustomObject *cachedObject = [myCache objectForKey:@"1"]; NSLog(@"Cached Object: %@", cachedObject); ``` When I try to access the cached object, I get an `EXC_BAD_ACCESS` behavior. I'm not sure if it's related to how `NSCache` manages memory or how `NSCoding` is implemented in my custom class. I have verified that the object is being set correctly in the cache. I’ve also tried adding breakpoints to trace the object’s lifecycle but still need to pinpoint the scenario. Any insights on why this might be happening or how I can debug it further would be very helpful. I'm working on a service that needs to handle this. Thanks in advance! This is happening in both development and production on Windows 11. My development environment is Windows 10. Any pointers in the right direction? I'm on macOS using the latest version of Objective-C. How would you solve this? Any pointers in the right direction?
